Storage Redundancy (1 / 16):

Your company operates an application that generates non-critical, easily reproducible data. They operate within a region with multiple Availability Zones. They wish to maintain a balance between data redundancy and cost-effectiveness.

What type of Azure storage redundancy should your company consider for their requirements?
How does the recommended storage redundancy option strike a balance between data redundancy and cost?
If your company decided to choose Zone-Redundant Storage, what could be the possible implications in terms of cost and data resilience?

Answer:

Your company should consider using Locally Redundant Storage (LRS). Since their data is easily reproducible and non-critical, LRS would provide sufficient data redundancy at a lower cost compared to ZRS.
LRS provides three copies of data within the same data center, providing adequate redundancy for your company's needs. As it doesn't replicate data across multiple zones, LRS is more cost-effective than ZRS.
If your company chose Zone-Redundant Storage, they would be paying for higher data redundancy that might be unnecessary given their data is non-critical and easily reproducible. This would lead to higher costs without substantial benefits in terms of data resilience.
